NEMA’s compact fluorescent lamps (CFL) index posted a reading of 210.1 during the second quarter of 2010, negating the 3.1 percent year-over-year gain during the previous quarter. CFL shipments decreased 4.2 percent on a quarterly basis following increases of 14.0 and 1.8 percent for the previous two quarters. Meanwhile, shipments of incandescent lamps decreased 2.8 percent on a year-over-year basis, as the index slipped to 57.0. This reading indicates shipments are less than 60 percent of 2006 levels.        

Although sales of both lamp types remain at lower levels compared to last year, CFLs continue to gain market share at the expense of incandescent lamps. The share of CFL lamps increased to a new high water mark of 26.7 percent while A-line incandescent lamps fell for the second consecutive quarter, decreasing to 73.3 percent.
